Honda has launched production of solid-state batteries to be used in electric cars, motorbikes and aeroplanes

Honda Motor has launched a demonstration production line for solid-state batteries in Sakura (Tochigi Prefecture, Japan). The line is based at Honda's R&D centre and is expected to be the first step towards mass production of the latest batteries, which are planned to be used in electrified vehicles in the second half of the 2020s.

Here's What We Know

The demonstration line has a total area of around 27,400 m² and is equipped with everything needed to test the promising technology. In particular for material mixing, electrode coating, cell formation and module assembly. Full production of batteries on this line is scheduled to begin in January 2025. Honda is also actively testing mass production and cost optimisation stages.

A special feature of Honda's solid-state batteries is the use of roll-pressing techniques, which increases the density of electrolyte layers and speeds up the production cycle. Engineers are also focusing on reducing energy consumption and other indirect costs by introducing new control technologies.

Honda plans to use solid-state batteries in a wide range of its products: cars, motorbikes and even aeroplanes. The company aims to reduce costs by scaling up production, which should make these batteries more affordable.

"The all-solid-state battery is an innovative technology that will be a game changer in the electric vehicle era," said Keiji Otsu, president of Honda R&D.

Honda's goals for the future: by 2040, all new vehicles from the brand must be electric or fuel cell-powered. Achieving this goal is based on new battery technologies that have high energy density, heat resistance and faster charging.
